How Your Colorado Paycheck Works
If you are a Colorado resident, your employer will withhold taxes from every paycheck you get. These taxes go to the IRS to pay for your federal income taxes and FICA taxes. FICA taxes go toward Social Security and Medicare. The amount withheld for federal taxes depends on the information you’ve filled out on your W-4 form. Remember you need to fill out a new W-4 when you start a new job or if you want to make changes (for example, after having a child).
In December 2017, President Trump signed a new tax plan into law. This plan led to updated withholding amounts for federal income taxes. It’s a good idea to recheck your W-4 in early 2019 just to make sure that you’re claiming the right number of allowances.
One big factor affecting your paycheck taxes is your marital status and whether you decide to file jointly or separately from your spouse. Filing as head of household will also change things. Any Coloradans who are common-law couples also have the option to file jointly.
Claiming dependents might affect your pay as well. Naturally, the frequency of your pay will also affect the size of your paycheck. The more frequently you get paid, the smaller each paycheck will be.

Coloradans are taxed at a flat state income tax rate of 4.63% of your federal taxable income, regardless of your income bracket or marital status.
If you work in Aurora, Denver or Greenwood Village, you will also have to pay local taxes. These taxes are also flat rates. If you work in Aurora, $2 is taken out of your pay every month if you earn over $250. In Denver, you’ll pay $5.75 monthly if you make more than $500. And employers in Greenwood Village will take out $4 every month if you earn more than $250.
Colorado residents who work in another state should be aware of the credit for tax paid to another state. If you live in Colorado and your income is taxable in another state, you may qualify for a credit for taxes paid to the other state.
If you’re in the military on active duty, you might not have state taxes withheld. To qualify you will need to make sure that you establish Colorado as your state of legal residence. You can do that by registering to vote in Colorado or purchasing property there. Once you do that, any money you get from being in active service doesn’t count as taxable income when figuring out Colorado income taxes (meaning you won’t be taxed in Colorado for that amount).
For those looking to move to Colorado, brushing up on the state’s income taxes is important, but you’ll also want to learn about what it’s like getting a mortgage in Colorado. Our mortgage guide has the important information to make sure you’re up to speed on what the mortgage market is like in the Centennial State.
Colorado Local Tax Rates
| City | Rate |
| Aurora | $2 per month on income over $250 |
| Denver | $5.75/month on income over $500 |
| Greenwood Village | $4/month per month on income over $250 |
How You Can Affect Your Colorado Paycheck
Changing how many allowances you claim on your W-4 is the simplest way to change the amount withheld from your paychecks. As mentioned above, you need to fill out a new W-4 whenever you start a new job, but you can also fill one out at any time. You should definitely recalculate your allowances if you have new dependents or recently got married or divorced. However, you can also change the number of allowances if you find that you’re consistently paying too much or owing money come tax time.
If you do regularly owe money when you pay your taxes, consider asking your employer to withhold more taxes from your paychecks. When filling out a new W-4, simply write in the dollar amount you want withheld. For example, if you want $60 taken out of each paycheck on top of the allowances you’re claiming, then all you need to do is write that amount on the correct line on the W-4. This means smaller paychecks, but think of it as paying more of your taxes over time so that you don’t have to pay a huge lump sum every year. Using a paycheck calculator like ours will help you see how your paycheck changes when you withhold more or less money.
Finally, one more way you can tweak your paycheck is to modify your pre-tax contributions. These lessen your taxable income and may even push you into a lower tax bracket. If your employer offers such benefits, think about putting more into things like a Health Savings Account, a commuter program or other types of flexible spending accounts. You might also want to increase how much you’re putting into your employer-sponsored retirement account, like your 401(k) or 403(b).

Most Paycheck Friendly Places
SmartAsset's interactive map highlights the most paycheck friendly counties across the country. Zoom between states and the national map to see data points for each region, or look specifically at one of the four factors driving our analysis: Semi-Monthly Paycheck, Purchasing Power, Unemployment Rate, and Income Growth.
Methodology Our study aims to find the most paycheck friendly places in the country. These are places in the country with favorable economic conditions where you get to keep more of the money you make. To find these places we considered four different factors: semi-monthly paycheck, purchasing power, unemployment rate and income growth.
First, we calculated the semi-monthly paycheck for a single individual with two personal allowances. We applied relevant deductions and exemptions before calculating income tax withholding. To better compare withholding across counties we assumed a $50,000 annual income. We then indexed the paycheck amount for each county to reflect the counties with the lowest withholding burden.
We then created a purchasing power index for each county. This reflects the counties with the highest ratio of household income to cost of living. We also created an unemployment rate index that shows the counties with the lowest unemployment. For income growth, we calculated the annual growth in median income over five years for each county and indexed the results.
Finally, we calculated the weighted average of the indices to yield an overall paycheck friendliness score. We used a one half weighting for semi-monthly paycheck and a one-sixth weighting for purchasing power, unemployment rate and income growth. We indexed the final number so higher values reflect the most paycheck friendly places.
